Comparative analysis of various models of phakic intraocular lenses (PIOL)implantation possibilityin patients with myopia


Eximer eye center


A prospective, open-label study included 61 patients (112 eyes) with myopia. The mean age of the patients was 29.4 ± 5.1 years (20-42), the mean follow-up period was 30.3 ± 10.6 (12-60) months. Three groups were determined: 1 - IPCL implantation (n = 40), 2 - Acrysof Cachet (n = 36) and 3- ICL (n = 36). In the postoperative period, we evaluated the UCVA, BCVA, IOP, pachymetry data, the number of endothelial cells and higher order aberrations.In the preoperative period, SE was -11.6±3.7, -9.59±1.97, and -12.3±4.8 in the IPCL, Acrysof Cachet and ICL groups, respectively.


At the maximum follow-up period, SE was comparable between groups (p=0.234). The mean decrease in astigmatism was 0.31±0.72, 0.45±0.62 and 0±0.57 D (p=0.008). Emmetropia (±1.0 D) was achieved in 87.5%, 91.7% and 94.5% of the eyes in IPCL, Acrysof Cachet and ICL,taking into account the corrected residual myopia in the long-term follow-up period. The frequency of improvement of BCVA by more than 1 line was 25.2%, 19.2% and 38.4% in these groups, respectively (p=0.151). Higher order aberrations (p = 0.039), vertical trefoil (p = 0.032), spherical aberrations (p = 0.001) were higher in the IPCL group than in ICL.


Implantation of phakic intraocular lenses is an effective and safe method for high myopia correction. The performed analysis showed that there were no significant differences in the functional results of phakic intraocular lenses IPCL, Acrysof Cachet and ICL implantation. Implantation of posterior chamber PIOL IPCL and ICL seems to be the optimal way to correct high myopia.
